Use of Internet and cell phones must be replaced with outdoor games as playing outdoor games refreshes our minds and also helps us to stay in touch with our friends. Excessive use of Cell phones and playing video games can lead to eye problems and also lack of concentration. 
These days, kids are more interested in social media sites and video games over playing outdoors. they stay in touch with friends through facebook, whatsapp and other such websites.
They forget the joy of hanging out with friends and getting some physical exercise.
